Embodiment
Referring to figs. 1 through Fig. 5, the utility model string item counterweight embodiment is described further.
As shown in Figure 1, a kind of string item counterweight, comprise multiple counterweight, described counterweight comprises balancing weight 1 and central strut 2, mounting hole 5 is provided with in described balancing weight 1, described central strut 2 to be arranged on balancing weight 1 and to extend balancing weight 1, one end that described central strut 2 extends mounting hole 5 is provided with stud 3, the other end of described central strut 2 is provided with threaded hole 4, multiple described central strut 2 head and the tail are threaded, described multiple balancing weight 1 and multiple central strut 2 one_to_one corresponding, described multiple balancing weight 1 is arranged at interval.Balancing weight 1 is cylindrical, balancing weight 1 center is provided with mounting hole 5, mounting hole 5 can allow central strut 2 pass, central strut 2 bottom is provided with round platform, round platform base is provided with flange 11, threaded hole 4(Fig. 1 is provided with not shown bottom round platform), balancing weight 1 clamping also can be lived through balancing weight 1 by central strut 2.By above-mentioned multiple balancing weights 1 and central strut 2, can mutually contact, as shown in Figure 2,3, a kind of string item balancing weight 1, comprises the central strut 2 of multiple balancing weight 1, the clamping of multiple and described balancing weight 1, described central strut 2 one end is provided with stud 3, the other end of described central strut 2 is provided with threaded hole 4, and multiple described central strut 2 head and the tail are threaded, and described balancing weight 1 can hang on described central strut 2 bottom, when balancing weight 1 is in suspension status, between adjacent balancing weight 1, leave space.
Central strut 2 and balancing weight 1 with the use of, single balancing weight 1 and central strut 2 can connect the stability coordinating and can improve in balancing weight 1 plus-minus process, can not make balancing weight 1 in use because central strut 2 moves, balancing weight 1 is in an unsure state, the effect of impact plus-minus balancing weight 1, and multiple balancing weight 1 and multiple central strut 2 are set with crossing, balancing weight 1 is connected on central strut 2, mutually contacted by central strut 2, easily and easily can change the general assembly (TW) of balancing weight 1 thus, and be threaded connection central strut 2 to couple together and namely stablize, there is the structural strength that can keep center-pole, balancing weight 1 hangs on central strut 2 bottom, when balancing weight 1 is in suspension status, space is left between adjacent balancing weight 1, convenient plus-minus balancing weight 1, balancing weight 1 can increase one by one, in central strut 2 decline process, second balancing weight 1 does not have the support of central strut 2, can stable and accurately drop on above first balancing weight 1, each balancing weight 1 can vertically superpose, for use provide convenient.
As shown in Figure 4,5, central strut 2 comprises flange 11, is provided with the groove 6 be connected with mounting hole 5 bottom described balancing weight 1, and described flange 11 is connected with groove 6 slippage.Balancing weight 1 center is provided with mounting hole 5, the chamber wall of described balancing weight 1 comprises groove 6 wall and support portion 7, groove 6 is cylindroid 8, described support portion 7 is round table surface 9, center-pole bottom is provided with keeper, described keeper is round platform, balancing weight 1 and central strut 2 just in time can be conflicted mutually, cylindroid 8 can centered by pole 2 in the process moved up and down, play freely movable space, can play to balancing weight 1 effect that corrects guiding simultaneously, ensure that balancing weight 1 center is consistent with the center of central shaft, such balancing weight 1 will neatly vertically be arranged in the process stacked, the round platform of central strut 2 coordinates with the round table surface 9 of balancing weight 1 simultaneously, increase contact area and improve stability, even if there is the environment of vibrations, balancing weight 1 can not rock, more stable state can be kept.
Central strut 2 also comprises round platform 10, described round platform 10 is wholely set on flange 11, described mounting hole 5 is inconsistent with described round platform 10, and flange 11 can increase the stability of central strut 2 further and have the effect of guiding, can adjust the position that balancing weight 1 falls to placing.Flange 11 can also prevent balancing weight 1 from dropping, after multiple central strut 2 is together in series, movable between the flange 11 that balancing weight 1 is just limited in adjacent center pole 2, thus improves the safe reliability that balancing weight 1 uses, and balancing weight 1 is not easy to lose or drop.
Central strut is provided with through hole 12.Under through hole 12 is arranged on the screw thread of stud 3, in the process that central strut 2 first place is threaded mutually, because round and smooth central strut 2 is not easy screw thread fixation, by arranging through hole 12, instrument can be used directly to be inserted in through hole 12, thus can very labour-saving turn central strut 2, be threaded also more firm, structure is more stable.
Specific operation process is as follows: be first set on central strut 2 by balancing weight 1, the bottom of second central strut 2 is connected at the stud 3 of the upper end of central strut 2, can the instrument of strip be inserted in through hole 12 in connection procedure, being threaded between central strut 2 is screwed by instrument, second balancing weight 1 is set on second central strut 2, circulation like this, is combined into the string item balancing weight 1 that quality can regulate.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
